Problem: Engine management light keeps coming on VAG-Com to diagnose



16556 - Fuel Trim; Bank 1: System Too Rich P0172 - 35-10 - - - Intermittent


Autodata reports possible cause: EVAP Canister Purge Valve, Fuel Pressure, Injector(s), HO2S


Anyone had this before & know where to start without replacing the valve or injectors

adjustment,before you do this check out the channel 6 readings,the fourth grouping should be between -10% and + 10%.when not carry out the above changes.

check channel 6 readings,the fourth should be between -10% and

+10%,when not change the airflow meter and have a basic settings reset by VAG
